Joe Pye Weed
PEI’s late summer landscape belongs to the Aster Family: yellow Goldenrods, purple Asters, and – one of my personal favourites – pink Joe Pye Weed (Eutrochium maculatum). There are five Joe Pye species in North America, but Spotted Joe Pye Weed, shown here, is the only one we have on the Island. This plant can be found across the province, though I see it far more commonly in Prince County, where it grows in damp roadside ditches, meadows, and coastal areas. Spotted Joe Pye

Staghorn Sumac
The Mi’kmaq have a name for each full moon of the celestial calendar, with August’s being the Berry Ripening Moon (Kisikewiku’s, pronounced gis-ig-ay-we-goos). This is indeed peak berry season on PEI, with SO many wild fruits on offer right now. But there’s one you may have overlooked: Staghorn Sumac (Rhus typhina). Staghorn Sumac is native to the Island, and was also used as an ornamental, meaning it can be found around towns, cities, and rural homesteads. It’s a beautiful

Tar Spot
Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. My inbox is overflowing with the question “why are so many Maple trees losing their leaves early this year”? In the trees I’ve seen, it’s due to Tar Spot fungus (Rhytisma acerinum). Tar Spot is the common name for several species of fungi in our region. There are a couple of native versions that infect native maples and willows, but the type that’s most prevalent now is

Horse Flies
I would have liked a better-composed and more in-focus photo of today’s PEI animal, but I was under attack by a hoard of these fierce creatures. If you’ve met them, you know what I mean: these are Horse Flies (Tabanus nigrovittatus or similar). The names Horse Fly and Deer Fly are often used interchangeably for any large, biting fly, but they are two different, albeit related, beasts. Horse Flies and Deer Flies are in the same family (Tabanidae), but Deer Flies (Chrysops sp

Mugwort
I get lots of questions about where to find certain PEI plants, but three species top the list: Common Elderberry, Serviceberry, and today’s subject: Mugwort (aka Common Wormwood Artemisia vulgaris). Unlike Elderberry and Serviceberry, Mugwort is not native to PEI. It was brought to North America as a culinary and medicinal plant in the 1600s and has been well-established on the Island since at least the mid-1800s. Mugwort is a perennial that spreads primarily by rhizomes

Goldthread
Today’s PEI plant epitomizes the saying ‘big things come in small packages’. Meet Goldthread (Coptis trifolia). Goldthread is a member of the Buttercup family (Ranunculaceae) and is common, though often overlooked, in mossy woodlands across the Island. Its delicate white flower (inset photo) – just a centimetre across and appearing for short time in May – is easily missed. Even the small, three-parted leaves usually go unnoticed unless you’re specifically looking for them,

Sarsaparilla
One of PEI’s most common woodland plants is often overlooked, occasionally misidentified, and fruiting now. Meet Sarsaparilla (pronounced ‘sass-parilla’, Aralia nudicaulis). Sarsaparilla is about 30 to 45 centimetres (a foot to 1.5 feet) tall and is divided into three branches, each with three to five leaflets (main photo). Those leaflets are often reddish when they first appear in spring, and they turn red again in fall. This, coupled with the old saying “leaves of three,

Foxtail Barley
As fields of grain ripen across PEI, you may have noticed a similar, though smaller, plant growing along roadsides, coastlines, and trails. Although this plant hangs out in human habitats and looks like it may have escaped from farms or gardens, it’s actually a native species: meet Foxtail Barley (Hordeum jubatum). Like our agricultural grains, Foxtail Barley is a member of the grass family (Poaceae). It’s in the same genus as the commercial Barley you may enjoy in breakfas

Bittersweet Nightshade
Today’s PEI plant is one that I’ve received many questions about, along with a request to do a post on it. So, meet Bittersweet Nightshade (Solanum dulcamera)! If these flowers remind you of tomato or potato blossoms, give yourself a gold star. Bittersweet Nightshade is in the same family (and the same genus) as those domestic crops, and is related to other familiar species including eggplant, peppers (both sweet and hot), gogi berries, and tobacco.

Jellyfish
There are certain, shared experiences that unite those of us who grew up on PEI. For example, getting storm-stayed in winter, going to the beach in summer, and having annual run-ins with Jellyfish! There are at least three species of Jellyfish in the waters around PEI: the Lion’s Mane (Cyanea capillata), shown here, the smaller and more cinnamon-coloured Atlantic Lion’s Mane (Cyanea fulva), and the white Moon Jelly (Aurelia aurita). Of the three, the Lion’s Mane is the most

Fireweed
PEI has wildflowers that are beautiful, edible, and ecologically important. Today we have an example that’s all three, and flowering now: Fireweed (Chamaenerion angustifolium)! Fireweed can be found across the Island, blooming in vacant urban lots, along rural roads and fields, and among forests impacted by 2022’s Hurricane Fiona. While it gets its name from an ability to recolonize land following wildfire, it doesn’t need fire to appear: any disturbance will do. Fireweed i

Fireflies
We humans tend to divide insects into two camps. There are those we don’t like (Earwigs, I’m looking at you!), and those we do, with no better example than Fireflies. I captured this lone Firefly’s flash at my home in central PEI recently and thought it’s time we took a closer look at these interesting insects! Fireflies are beetles, not flies, and not all have ‘fire’ – many species are daytime-fliers that use pheromones, rather than light, to communicate. The night-flying,

Ox-eye Daisy
This week, we’re looking at a couple of edible non-native wildflowers that are in season right now. On Monday, it was Tufted Vetch; today we have Ox-eye Daisy (Leucanthemum vulgare). Most people are familiar with Ox-eye Daisy’s distinctive white petals (ray flowers) surrounding the golden-yellow centre (disk flowers). This cheerful-looking plant can be found across the Island, pushing up through cracks in sidewalks, growing among the stone landscaping of highway dividers, l

Common Comfrey
There are some PEI plants that, when I find them, suggest there was once a homestead nearby. Wild Apples and abandoned Lilacs are two examples, but so too is Common Comfrey (Symphytum officinale). Comfrey is native to Europe and parts of Asia and was brought to North America as a medicinal and ornamental plant in the 1600s. This plant’s name attests to its long history of medicinal use: Symphytum is from ancient Greek words meaning ‘unite’ and ‘a plant’, while officinale wa

Red-mouth Bolete
I love meeting a new-to-me mushroom, and so was quite happy when I found these among my favourite patch of King Boletes (aka Porcini) last week. Meet the aptly named Red-mouth Bolete (Neoboletus subvelutipes). Followers of this page will know that mushrooms with spongy pores rather than gills, folds, or teeth under the cap are boletes. (Not all boletes have spongy pores, but mushrooms that do are boletes. And if you haven’t been following this page, you can get caught up on

Starry False Solomon's Seal
When we think about wildflowers, coastal areas often get overlooked in favour of fields, forests, and roadsides. But that means missing some of PEI’s loveliest native plants, including Starry False Solomon’s Seal (Maianthemum stellatum). Starry False Solomon’s Seal is a relative of Wild Lily-of-the-Valley, which I introduced you to earlier this spring. If you guessed these plants are members of the Lily Family (Liliaceae), you’d be sensible, but wrong! The genus Maianthemum

Alternate-leaved Dogwood
It’s great to see landscaping with native plants becoming mainstream. Many nurseries now carry at least some native species and seed mixes, while PEI’s Rural Beautification Society has added a Native Planting & Biodiversity category to its popular annual competition. The Island has many common, native plants that make beautiful additions to backyard gardens. One example: Alternate-leaved Dogwood (Cornus alternifolia). PEI has four native Dogwoods, which are all easy to spot

Is this edible?
This year’s damp weather may not be popular with everyone, but it has been great for mushrooms! The abundance of fruiting fungi has brought out a crop of social media posts asking about edibility. Here are some tips to help you ask the right questions and get reliable answers! I love encouraging people to try wild plants and fungi, but I cringe every time someone asks “is this edible?” That should never be your first question; instead, start with “what is this, and how can I

Common Lilac
Some PEI plants are inextricably linked with people – not only in how the species arrived here, but also in their ongoing social and cultural value. I can think of no better example than the Common Lilac (Syringa vulgaris). Lilacs are not native to North America but were among the earliest flowers brought by European settlers. Considering the harsh conditions and limited space on ships crossing the North Atlantic in the 17th century – not to mention the utilitarian worldvie

Tartarian Honeysuckle
Public awareness of invasive species is high now, but that hasn’t always been the case. In the 1800s, if a foreign plant was edible, medicinal, or pretty, it was brought to North America without much thought. As a result, we are now dealing with dozens of problematic species, including invasive Honeysuckles. Tartarian Honeysuckle (Lonicera tartarica) was introduced to North America from Asia in the 1840s as an ornamental garden shrub. The same traits that make it attractive
